Voice over New Radio or Voice over 5G (acronym VoNR or Vo5G) is a 5G high-speed wireless communication standard for voice services, using mobile phones and data terminals, including Internet of things (IoT) devices and wearables.[1] 5G networks, like 4G networks, do not natively support voice calls traditionally carried over circuit-switched technology. Instead, voice communication is transmitted over the IP network, similar to IPTV services. To address this, Voice over NR (VoNR) is implemented, allowing voice calls to be carried over the 5G network using the same packet-switched infrastructure as other IP-based services, such as video streaming and messaging.
VoNR fully utilizes the 5G standalone (SA) core and can have better voice quality than its 4G predecessor Voice over LTE (VoLTE).[2] Call setup time is faster than VoLTE due to the inherent lower latency of 5G NR. VoNR removes the LTE anchor allowing the voice call to stay on a 5G network.
VoNR (Vo5G) calls are usually charged at the same rate as other calls. To be able to make a VoNR call, the device, its firmware, and the mobile telephone provider must all support the service in the area, and be able to work together.
